HomeBackend DevelopmentPHP Tutorial PHP,小弟我想用正则表达式得到数组(@中肖,@尖,@地s_3法,@在有)这四个数组元素,不包含@空格

PHP,我想用正则表达式得到数组(@中肖,@尖,@地s_3法,@在有)这四个数组元素,不包含@空格。
$str = '@中肖 @尖 困@地s_3法 @在有 @ ';
preg_match_all('/@+\s/', $str, $matchs);
想得到@与空格之间的xxx(可为中文与英文,下划线等符号)
我这样写是错了。求大侠帮手。谢谢了!

当然有其他方法可以得到数组(@中肖,@尖,@地s_3法,@在有)也行,求赐教!

------解决方案--------------------
$str = '@中肖 @尖 困@地s_3法 @在有 @ ';
preg_match_all("/@\S{1,}\s/", $str, $matchs);

\S (大写) 表示所有非空白字符, 后跟 {1,} 表示必须至少有一个匹配字节
------解决方案--------------------
我大意了,没有必要再在\S后跟一个\s,这样做反倒画蛇添足
------解决方案--------------------

PHP code
[liangdong@bb-browser-test00.vm.baidu.com php_project]$ php main.php 
Array
(
    [0] => @中肖 
    [1] => @尖 
    [2] => @地s_3法 
    [3] => @在有 
)
[liangdong@bb-browser-test00.vm.baidu.com php_project]$ cat main.php 
<?php $content = "@中肖 @尖 困@地s_3法 @在有 @ ";
$n_match = preg_match_all('/@.* /U', $content, $matches);
if ($n_match) {
        $res = array_filter($matches[0], function($item){return trim($item, "@ ");});
        print_r($res);
}
?> <div class="clear">
                 
              
              
        
            </div>

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
